FIBERFHANDLING MECHANISM.

T0 all wim/m t 92mg/ concer/1i.'

Be it known that I, Lun. HOLLAND-Lara, a citizen of the United States, residing at Gai( Park, in the county of Cook and State of Illinois, have invented certain new and useful. Improvements in Filoenliandling Mechanism, of which the following is a full, clear, and exact specification.

This invention relates to mechanism for handling fiber, such as hemp, flax, sisal, etc., and more particularly, to means" for guiding the fiber in its passage from one machine to another and for depositing said material in position to be fed to the second machine in a direction transverse to its length.

The particular problem 'which led to 'the present invention is that of handling hemp and of properly positioning hemp for its feeding movement through a. sentcher after the hem has passed through the hemp brake. rEhe most `common type of hemp brake is the roller brake which comprises a. plurality of pairs of corrugateifl rollers between which the hemp stalks are fed longitudinally. Hemp sent-chers are used to clean the hemp after it has heen passed through the brake and 'to comb out the woody material or hurds from thel'iemp fiber.

In one forni of scutcher the broken hemp is gripped :intermediate its ends, and the ends of the fiber are combed out, thereby removing the hurds.

From this brief outline of the braking and scutching operations, it will he seen 'that the hemp is fed longitudinally thrmigh the roller brake, but is fed through the scott-her "n a `direction transverse to its length, or substantially at right angles to its direction of movement through the brake. i

In view of this change in the direction of feeding movement, itis necessary either by manual or mechanical means to receive the hemp as it comes from the biale and-to guide and position, or deposit the hemp in such a `manner that it may be gripped :intermediate its ends and be fed through the scutcheii'. The invention has for its object, therefore, to receive, guide and position or deposit liber,

such as broken hemp, in such a manner that the direction of feeding movement of this material may be changed.

A. further object is to provide means for receiving, guiding and positioning liber in such a manner that the ber is so deposited Specification of Letters Patent.

that it may be fed in a direction transverse to its length or transverse to its former direction of feeding movement.

Another object is to clamp and hold the iiher'in a position against the fixed member as the remaining part of the ber is being guided and positioned upon said fixed member for :feeding movement.

A. still further object is to hold the liber at one point in its length as the remaining portion of the fiber is so guided and positioned that it may be fed in a direction transverse to its length, but to hold the liber in suoli amanner that this holding means is rendered ineffective or inoperative before the guiding` and positioning means has completed its function or operative movement.

A still further object is to provide means for varying the point of release of *the clamping or holding means with respect to the cycle of movement of the guiding and positioning means.

`With these objects in view and vvith furtherobjects which Will appear as the description proceeds, the invention consists briefly of mechanism which is interposed between the hemp brake and the hemp scutcher and receives the broken hemp from 4the brake or from a conveyor leading from the brake, and guides and positions the broken hemp in such a manner that it may be fed through the scutcher in a direction transverse lto its length. in this instance the mechanism in which the invention is `embodied is mounted upon a fixed support arranged longitudinally with respect to the axis of the scutcher and adjacent and slightly below the delivery end of a conveyor which receives the hemp from the brake. its the hemp passes over the delivery end ofthe conveyor it Awill fall by gravity adjacent one side of the fixed support, and means is provided for clamping the hemp `against one side of the fixed supn port and for guiding the remainder or free end portion of the hemp over the top of the support and to a position in which the said end portion rests against the opposite side of the fined support. A feeding member passes along the upper surface of the fixed support, and as this member is preferably in continuous operation, means is provided for releasing the clamping or holding means which retains the hemp in position against the support before the hemp guiding and positioning means has completed its movement in a direction to position the free ends of the hemp.

In the embodiment of the invention illustrated, means has also been provided for normally clamping the hemp against the de- 'livery `end vof the conveyor which receives the hemp from the hemp brake, and this clamping means is so connected to the guiding and positioning means that as the hemp is received and acted upon by the guiding and positioning means, the means for holding the hemp in engagement with the delivery 'end of the conveyor is automatically released.

One embodiment of the invention has been illustrated in the` accompanying drawings, and in these drawings i Fig. l is a front elevation showing my improved mechanism mounted on a lined support adjacent ahemp scutcher, and also showing the delivery end of the conveyor which receives the hemp from the brake;

Fig. l0 is a detail planr view, partly in section, illustrating the adjustable means tor varying the period ot action of the clamping or holding means, l

Referring to Figs.v l to 3, the delivery end ot the conveyor which receives the hemp from the brake is illustrated at 20, means in the form of a roller 2l being provided tor normally holding the hemp in Contact with the conveyor. Roller 2l is carried by arms '22 pivoted at 23 to the conveyor casing, and

this roller yis normally held in engagement with the conveyor by gravity. As illustrated in Fig. l, one ot the arms 22 is extended beyond the pivot 23, as shown at 24,

and shock absorbing or cushioning means is provided and co-operates with the arm QQ, this means comprising a rod Q5 which passes through a suitable aperture 2G in the arm 24, and is provided with a nut or head 27 which normally `rests against the arm Q4. The rod 25 is passed through a lug Q8 earried by the casing oit the conveyor and is encircled by a coil spring- Q9 which is interposed between a nut 30 and the lug 28. A iXed supporting `member 3l is mounted on framework 32 adjacent the hemp seutcher 33 and an endless conveyor 34 is suitably supported on sprocket wheels 3o and 3G earried by the supporting member and feeds the hemp into the scutcher The hemp which has passed between the pairs oi rollers of the roller brake is fed by the rollers on to the end of the conveyor 20, and travels on said conveyor to the delivery end thereof.

The object of the present invention, as stated above, is to receive the material as it comes from the roller brake and the conveyor, and to position it in such a manner that it may be gripped and 'fed in a direction transverse to its length through the, scutching mechanism.

Referring to the present structure, therefore, the problem to be solved is to receive the hemp trom the delivery end of the conveyor 2O and to position the hemp on the supporting member 3l in such a manner that the chain Bel will engage the hemp intermediate its ends and preferably at a medial point, and will feed the hemp in a direction transverse to its length.

As above pointed out, the improved hemp handling means is made up ol two parts, namely, the means for clamping or holding the hemp against the supporting member C-ll. and the means tor guiding and positioning the hemp on said supporting member as it is being held.

In the embodiment of the invention illustrated, the guiding and positioning mechanism is positively actuated, and this n'iechanism engages, during a portion ot its morement, the clamping` and holding means, thereby rendering this clamping means operative during a portion of the movement et the guiding and positioning mechanism. This last-named mechanism ispivotally supportedon a casting 37 rigidly secured by bolts 38 to the supporting member ill, and provided with the outwardly extending pivot pin 39. The clamping and positioning means is carried by a main casting l0 piroted on the pivot pin 39, but secured against removal by a Cotter pin 4l. An arm l2 is bolted to the casting -lO as shown at 113, and i is provided with a laterally extending handle 44 by means of which this arm is manually operated. A rod 45 is rigidly clamped to the arm 42 and extends in Ya direction toward the seutcher mechanism, or

along the longitudinal axis of the supporting member 31. A VYsecond arm 46 is also rigidly secured to the casting by bolts 4, the arms 42 and 46 being disposed at substan tialljT a right angle to each other. A shield or guiding member 48, arcuate in cross seci tion, is secured to the rod 45 and to a rod 49, carri ed `by the arm 46 adjacent its outer ein tremity. From the showing in Figs. l, 2 and 4,it Will be seen that this shield l? forms `with the adjacent surface of supporting' ineinberl a pocket or receptacle for receiving' and guiding' the nemp as it .falls from the delivery end of the conveyor 20. An angle iron frame member 5() is rigidly bolted to the supporting member 3l below the guiding; andpositioning means, and is provided at one end with an outwardly extending por tion 5l., to Which are connected the ends of counterbalancing springs, hereinafter described, and at its opposite end the member 50 is provided With an outwardly and up- Wardly extending portion 52 Which forms `a rest for the arm 42 When said arm 1s disposed in its normal or inoperative position. The casting 40 is also provided with an otlset lug 53 which in turn is slotted as shown at 54. A member 55 is adjustably secured to ing and positioning means aboutits pivot through the initial movement thereof, and also as shown in Fig. 5, the spring' acts as a coiniterbalance or cushioning spring 'when the j j )ositioning and `guiding;r means has reached its limit of Aoperative movement. By adjustingr the member 55 with respect tothe lug 52S, the effectiveness of this spring and the point at which the :torce olf the spring takes effect may be varied. j As above stated, in the present embodi- `ment ol the invention, the means for clamp- I ing` and holding the hemp against the sup porting member 3l is actuated by means ol the y liding' and positioning member, and next inorder I will describe the portions or parts ot the guidingl and positioning1 mecha nisms which perform this tunction.

The casting 4() is extended below the pin ill) upon `which this casting is pivoted, this lower portion being' substantially triangular in outline, as shownatf59. The extreme lower `edgzj'e oi this lower portion of the cast ing; is jju'ovided with a laterally extending flange G() 'which extends from a point 6l on Athe castingr to a point 62, the latter point being located at a distance 'from one edge of the casting. The flange forms a cam sur- `vided with a downwardly eiictendingI lug (S9 having a serrated lateral edge, as shown at 70, which engages a serrated edge 7l. 'formed on the casting 40. The lue,r 69 is secured to the casting 40 by means of a bolt l0 which passes through an arcuated slot 'l2 :termed adjacent the lower end oit the casting' 4G. lit the operator therelfore desires the holding or clamping means toremain operative :tor a longer time, the extension G8 of the flange 60`is adjusted in a direction toward the ad jacent edge of the casting` 40, or in a clockwise direction (see Fig. l), and i'l the opera tor desires the holding; or clampingF means to be released earlier this extensionY G8 is ad justed in the opposite direction.

The arni G4 above described is a main actuating ineniber li'or the clampine` un d hold in?,` means, and the structure oil; this holding or clamping' means and the connections be tvafeen the arm G4 and this means lwill next he described. j

ln addition to the arm (S4 is pivotally mounted on the casting' haring secured thereto an arm "[4 which carries at its outer end rod Q75, the rod entending,r laterally from the arm in a direction toward the scutching' machine, or parallel to the longitudinal anis ott the supjan-ting` member 3l. The casting lf-l also has seciu'cd thereto at an anglo to the arm 74 an arm 7G which is connected at its outer end to a rod 77, this rod being bent upwardly at an angle showi. at 78, anfl being slidably connected at its upper end with a laterally euctt-indingr lun' fl() which is carried by the outer extremity of the arni Q2 :nid adj acenf: the roller @tops 8l und SQ, are carried by the rod and limit the movement oit the lug Si), a buller sprinpji` 83 being' carried by the rod adjacent the lower stop 89.. 'From this description it `uf'ill be seen that as the arui '76 is mover. about its pivot in an anticlockwise direcl'on (see lf 3) the rod il' will be moved vertically and will. lili't the arm 22 and u'f'ith it the roller 2l.. lhese elements areso connected together that the :rollt ill will be lil'ted. approxiniately at the period in the movement ol.i the handling mechanism rod in the `when the rod holds the hemp apninst Athe `juism illustrated in Fig. 3. Since the cam cl il `or tlange 60 carried by the casting Ll() must structed that it will engage the roller durinej its movement in one direction, but will yieldL during its moven'ient 1n an opposite direction in such a manner that neither the roller nor the engaging surface will be injured. lorovision has been made for ullilling this condition, and the means for accomplishing this result comprises a cam member 84 which is pivoted at 85 to the casting ed As illustrated in Figs. 8 land 9, the membei` 84 is laterally offset, as shown at 96, this oliset portion being normally disposed in a position adjacent the ledge 61 ot the flange 60, thus forming an extension ot said flange. A portion 87 of the pivoted member Sd; disposed on the opposite side ot the pivot ot said member from portion 86 locatedadjacent the outer surface of the casting ll-G, and is provided at its rear end with an apertured lug portion 88. rllh'e casting d() has preferably formed integral therewith an oil'- set lug 89 so located with respect to the pivot ot the member 841- that the lug 88 carried by the pivoted member will be disposed directly beneath this lug` 89. fr rod 90, having on one end a head 91 is passed through the apertured lug S8 and through the offset lug 89, and carries a coil `spring 93 which engages at one end a cotter pin 92 which passes through the' rod 90, and at its opposite end the upper surface ot the lug 89. From this description it will be obvious that the spring 93 normally retains the pivoted member Sl in the position shown in the drawing.l and that the piVoted member Slmay yield. upon the return movement of the guiding and positioning mechanism in order to permit this mechanism to assume its normal position shown in Fig. l, and to pass over the roller 65v which will engage the under surl'ace of the pivoted member Sel during the return movement of the latter.

The clamping and holding means is operatively connected to the arm 64e by means or' a spring 94 which is secured at one end, as shown at 95, to the free end ot the arm (Self and at its opposite end is adjustably secured to the lateral offset end 96 of an arm 97, this latter arm being rigidly secured by suitable means, such as bolts 98, to the arm 7 l and 76, which carry the clamping and holding rod 75. rl`he tension on the spring 94 is so adjusted by means of the screw-threaded connection 99 between this Spring and the oii'set end 96 ot the arm 97 that this spring normally acts as a rigid connection between the actuated arm 64C and the arms 74 and 7 However, when the rod 7 5 has been adjusted to a position in engagement with the side surface et the support-ing member 31, the spring 94- is expanded as shown in Fig. 3,

and provides a resilient connection maintainH ing the rod 75 in engagement with the su p porting;n member 31 until the roller G3 is released from the cani action ol the extern sion 68 of the flange (5() carried by the cast ing Ll-O A counterbalaneing spring 10() is also provided for the arm 64, beingr connected at one end to aI lug 101 carried by the arm 6&2 and being adjustably connected at its opposite end as shown at 102 to the portion 51 of the frame member 50. Means has been provided for supporting the arm 7l in its inoperative position, or position oi' rest, this means comprising a laterally extending stud 103 suitably supported on the upwardly extending and oit'set portion 52 ot the vtraine member 50, and on a substantially parallel upwardly extending portion oi the .traine member o0.

Having described the construction ot my improved holding and clamping means and of the mechanisml'or guiding and positioning the hemp, l will now define the operation of these constructions.

The normal position, or position oi rest ot these structures is illustrated in Figs. 1 and ll, and in this position arm Il2 rests against the stop formed by the upper end ot the poi'- tion 52 et the frame member 50 and the arm 74 rests against the stop formed by the stud 103 also supported by the 'trame member 50. Atft-er one -,t'eeding ot' hemp has been passed through the hemp brake this hemp will travel upwardly on the delivery conveyor over the delivery end 20 of this conveyor. As the hemp falls by gravity from the delivery end 20 of the conveyor and reaches a position in which substantially half of the hemp is disposed below the upper surface ot the supporting member 31, the operator grasps the handle 44C and swings the arm 112 and the guiding and positioning means earried thereby in an anti-clockwise direction. As this guidingand positioning means is swung in this direction, the pivoted member Sd carried by the casting Ll() will engage. the under Surface oiC the roller G3 and vwill swing the arm Gd about its pivot (l5 and through the spring connection 9i, and arm 97 will also swing the arm 7d and the elaniu ing and holding rod 7 5 in an anti-clockwise direction. lflilhen the rod 75 has been swung to a position in engagement with the side surface o't the supporting member 31, as shown in Fig. 3, the spring 94 is expanded, thereby resiliently holding this rod in engagement with the supporting member. As one portion of the hemp is being held in engagement with the supporting member by the rod 75, the `tree ends ot' the hemp will be engaged by the rod Ll5 and guiding shield 48, and will be carried over the top surface ot the supporting member 31 in a manner which will be clear from the illustration in Figs. 3 and 5. Then the guiding and posi- Acw `tioning means has reached a position above the supporting member. as shown in Fig. 3, the roller 63 will be released :trom engage ment with the cam carried by thecasting 40.

i and the arm 7i and rod 75 will drop by gravity to their normal or inoperative position, this return movement of the clam ping and `holding means being cushioned by the spring tion of carrying the hemp over the upper surface of the supporting member and properly positioning this hemp for feeding in a direct-ion transverse tov the length thereoi". Thismechanism is then released and is re turned to its initial position by means of the spring 57, and during its return movement the `roller 63 will be engaged. by the under surface of the pivoted member 84 and will swingthis member about its pivot againstl the tension of the spring 93 until the` pivoted member has passed the roller, whereupon it will be returned to its normal position. As abovestated in this specification, the point of: release of the clamping and holding means is determined by the adjustment of the extension 68 of the flange or cam 60 carried by the casting 40, and by means of this adj ustable extension thehemp can be held in engagement with the supporting member 31 for a greater or less length of time. It is i desirable, however, that this clamping and holding means be `released as soon as the guiding and positioning means has swung the free ends of the hemp to a sufficient distance to` insure their being properly placed on the `supporting member, since the con'- `veyor 34 `is constantly in operation, and if the hemp is held for too long a period the fibers might be broken or tangled by the rc tarding action.

From the above description of the construction and operation of my improved hemp handling mechanism, it will be evi dent that an efficient and practical construe tion has been provided for accomplishing the objects outlined, and a construction by means of which the hemp may be received from a hemp brake and may be quickly and accurately positioned in such a manner that it may be fed in a direction transverse to its length into a scutcher or any other desired cleaning mechanism. The use of this con struction is simple and the operator need not be particularly skilled, since it is only encumbent upon him to manipulate a single handle when the hemp has been delivered from the braking mechanism` By means of this single manipulation by the operator the clamping, holding, guiding and positioning mechanism is set in operation and released, and the actuation of these parts is so timed that careless operation will have no effect on the performance of their functions if the initial. movement ofthe mechanism is prop-` erly timed.

W'hile l have in the above specification described one embodiment oi my invention and have referred more particularly to hemp as the liber operated upon, it will be obveus that this mechanism is adapted for use` in connection with other fibers, and that vari4 nus modifications and changes in the construction may be made without departing irom the spirit and scopeoi' the invention, as expressed by the Following claims.
